Note we're using the in-favor HTML class instead of the in_favor class
so we're consistent with our conventions for HTML classes and because we
use the in-favor class in similar places.
Also note the styles of the legislation process annotations/comments
buttons is now similar to the styles in the other sections. Previously,
the colors didn't have enough contrast and there was a very strange
margin between the "thumbs up" icon and the number of people agreeing
(that margin wasn't present between the "thumbs down" icon and the
number of people disagreeing).
